At least for the foreseeable future, I'm going to be buying a Pixel and immediately installing GrapheneOS on it whenever I need to upgrade my phone.
The experience is not perfect, and especially if you opt to not even keep the sandboxed Google Play Services, lots of apps just won't work. But it's a trade-off I'm happy to make.
My Pixel 5 is exactly what I wanted. The problem is that Google only gets it this right every few generations, and it doesn't always coincide with me needing a new phone.
Either they forget the size of human hands, the EUR:USD exchange rate, or some other obvious thing that makes their current generation a no-go.
